Traveller notes

Airport pickup
Incheon has 5G at the gate on SK Telecom, KT and LG U+. Install Naver Map and Kakao T before you fly; Google Maps barely works for directions in Korea.
Hotspot and calls
Allowed on most plans. Korean networks are among the fastest anywhere, so a 1 GB a day habit becomes 2 GB without noticing.
Where the network is weak
Seoul, Busan and the KTX are excellent. Seoraksan and Jeju's inland trails drop to 4G or nothing; the DMZ tour area is deliberately limited.
Local SIM alternative
Many Korean apps want a Korean number for sign-up. For a week the eSIM is enough; for stays over two weeks, a KT or SK tourist SIM with a number from the Incheon counters is worth it.

Paying from India

Providers take Visa and Mastercard, including Indian debit cards enabled for international use. Expect a 2 to 3.5% forex markup from your bank. UPI, RuPay-only cards and Paytm are not accepted. Apple Pay and Google Pay work where your card does.

Which eSIM is best for South Korea from India?

Right now it is Ubigi with the 10 GB · 7 days plan at ₹1,135. It has a Pakka Score of 8.3 out of 10 for South Korea, based on 93 traveller reviews of Ubigi there, and it is sized for a 7-day trip.

How much does an eSIM for South Korea cost?

Right-sized plans for about a week start at ₹946 from Airalo. Our pick costs ₹1,135. Prices are converted from USD daily, so expect small movements.

Which network does Ubigi use in South Korea?

Ubigi rides on KT in South Korea. The destination score reflects how that network performed for previous travellers, which is why the same provider can score differently in a neighbouring country.

Is an eSIM better than a local SIM in South Korea?

Many Korean apps want a Korean number for sign-up. For a week the eSIM is enough; for stays over two weeks, a KT or SK tourist SIM with a number from the Incheon counters is worth it.

Where is mobile coverage weak in South Korea?

Seoul, Busan and the KTX are excellent. Seoraksan and Jeju's inland trails drop to 4G or nothing; the DMZ tour area is deliberately limited.

Can I use hotspot on an eSIM in South Korea?

Allowed on most plans. Korean networks are among the fastest anywhere, so a 1 GB a day habit becomes 2 GB without noticing.

Will my Indian card work to buy an eSIM?

Visa and Mastercard debit or credit cards with international use enabled work with every provider we list. UPI and RuPay-only cards do not. Your bank will add a forex markup of roughly 2 to 3.5%.

How much data do I need for 7 days in South Korea?

For normal use, maps, WhatsApp, social media and a few video calls, budget about 0.7 GB per day, so around 4.9 GB for 7 days. Heavy users who stream or hotspot should double that.

When should I install the eSIM?

Install it on Wi-Fi before you fly and keep it switched off until you land. Incheon has 5G at the gate on SK Telecom, KT and LG U+. Install Naver Map and Kakao T before you fly; Google Maps barely works for directions in Korea.
